Ok im running a stage 1 and agp wga. What is the point of getting a map clamp? From my understanding all it will do is lean out your a/fs and help you not pull timing. So what is the point of leaining out you a/fs when you can just up your boost. wont that lean out your a/fs?? I have a wideband i can use, and i know not to mess with this unless you can monitor your a/fs. I just dont understand why you would need this. It seems kinda dagerous if you ask me. But please clear it up, and if getting one is a good idea for me let me know, they are pretty cheap if they actually help you out.
Its a matter how much you up your boost inorder to lean out your car without a tuning device. Even having too many mods with no enough fuel mods will lean out your car. The problem is with S1 if you have no way of clamping the voltage on the mapclamp and the PCM sees that its being ran passed it parameters (too much boost) it will begin to pull timing and the car loses performance. You will also want to monitor knock as well. A lot of people think they are good because they have a wideband and their AFR's are in the safe range 11.5-11.8. But most are not safe. Just because your afr's are safe doesn't mean you won't/don't have any knock and your timing might be out of whack. I recommend a Scangauge as well, as its a tool for tuning and monitoring different aspects. I've tuned these cars to safe AFR ranges and still had knock and some with timing squed... all this was seen on a Scangauge. I've even seen it with my car as well. AFR's, Timing, Knock need to all considered and monitored while tuning these cars not just AFR's. A map clamp all it does is clamp voltage on your map sensor. So your pretty much tricking the pcm on how much boost your running, reducing fuel and leaning out your afr's. Its a cheap version of a piggyback and the cheapest alternative you can use for "tuning" your car. I do not like them one bit. Some have had good experience with them and some have not. I'm part of the group that didn't have good experience with a mapclamp. My experience... WOT on a highway at around 120mph the mapclamp failed and my car went extremely lean on my wideband (red light to the end of my Uego don't remember the number reading) and the car starting running like crap. Cut the mapclamp off and the car was back to normal. Brand new mapclamp and only a week old. Installed correctly and tuned correctly. Week later FAILED! They can fail at any moment and any given time.
sounds like what i thought. On a side note is it wise to get a fuel return line? And is a piggy back fuel controller even needed with a stage 1 and return line kit?
From the information I've gathered. Getting a returnline is great when it comes down to tuning fuel as now you have control of fuel pressure. As you can work with the fuel itself and then adjust with a piggyback like the SAFC. Depending on your goals S1 plus returnline will be plenty of fuel if sticking with the stock turbo. So in other words... if you plan on sticking with S1 and want to up the boost to a 21-22psi spike. Get a returnline and a SAFC. A returnline is just an alternative for more fuel and an alternative to running S2 injectors for a stock turbo setup.
how excatly do you fix know retard? take the boost levels down, or get some octane booster? what is the best move? I found a CCA BFMIC for $150 used. Dose anyone have any experience with the cca Ic?
To fix knock, there's a few alternatives. If the knock sensor is not damaged then to reduce knock you would either need to lower your boost level or run higher octane fuel. You could also run a W/I kit. Too much fuel will cause "rich" knock, which I've experienced. Reducing boost would be the best move unless you can afford to run higher octane fuel all the time. As for the CCA intercooler. I have no experience with them.
i run 93 octane all the time. nothing else, would a bottle of octane booser help out, do they even do much, or would i prett much have to start mixing race gas with 93 to get a higher octane?
There's only a few octane booster's out there that people claim will do something... two that I can think of is Torco and Nos. You would have to start mixing race gas with 93. I run 93 all the time, no reason yet for me to run/mix race gas.
